On Monday afternoon Leonardo DiCaprio and his lady love Toni Garrn went to Records Surplus in Los Angeles, and the lovebirds bought several bags worth of merchandise. Looks like Leo's giving his much younger lady love a crash course on some of his fav bands -- you know we're gonna see these two at Coachella this weekend!

Leo and Toni may be 18 years apart (she's 21, he's 39), but that's not what's so shocking to us -- it's the fact that they're coming up on their one-year anniversary! Is it possible that Leo, who is famous for dating just about every hot model we've ever heard of, is finally ready to settle down? Or is Ms. Garrn just sitting on borrowed time?

Seeing as Leo's dated gals like Gisele Bundchen, Bar Refaeli and Erin Heatherton, it's a fair question to ask! Not to mention that he has the habit of loving 'em and leaving 'em...
